HORSESHOE.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed July 18, 1906. Sena-1N0. 326,730.

To all whom it may concern:

Be it known that we, MARcUEnrrn DE W. MUDGE and HENRY H. MUDGE, citizens of the United. States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented new and useful Improvements in Horseshoes, of which the following is a specification.

Our invention relates to an improved means for screw-fastening a calk to a shoe, whereby it is securely held in place and may be readily removed.

Other advantages attending the use of our improvement will appear later on.

In the accompanyingdrawings, Figure 1 is an under side plan view of a horseshoe embodying our improvement. Fig. 2 is a vertical section through the shoe and the toecalk on the line a a of Fig. 1. Fig. 3 is a perspective view of the toe-calk removed from the shoe. Figs. 4 and 5 are similar views of the inside and outside heel-calks, respectively. Fig. 6 is a perspective view of one of the screws used in attaching the calks to the shoe.-. Fig. 7 is an end view of the head of the screw. Figs. 8, 9, and 10 show modifica tions hereinafter explained. Fig. 11 shows in perspective three equivalent forms of the recess formed in the-shoe to receive the calk base-plate, together with the screw-holes and tenon-mortises.

Similar reference characters indicate similar parts in the respective figures.

' Referring to the drawings, A represents an off or right front shoe provided with a toecalk and heelcalks, the inside heel-calk running straight with the shoe and the outside calk across the heel thereof. These calks are secured to the shoeas follows: Each calk 1 is provided with a base-plate 2, having a tenon 3, which fits in a mortise 4 formed in the shoe. The base-plate 2 of the toe-calk is preferably furnished at each end with a countersunk hole 5, into which fits flush with the under side of the plate the conical head .6 of a hollow or cylindrical screw 6, which screws into a threaded hole 6 in the shoe, and the base-plate 2 is also provided with a-central tenon 3, which fits the mortise 4 in the shoe. The central opening 6 of the screw 6 is of polygonal form and in the drawings is shown square, although it may be of any suitable shape, and is adapted to receive a wrench, one

style of whichthat is tosay, the single-handle kindis shown in Fig. 2. The wrench may be of other form as, for example, one with two handles. The screws 6 may bythe use of the wrench be loosened and taken out and the calk 1 detached by removing: its tenon from the mortise 4. The same general mode of connection applies to thetwo heelcalks, Figs. 4 and 5, but one screw being used and the tenon 3 being, as in the case of the toe-calk, immediately above the calk.

We do not limit ourselves to the size of the base-plate or the number of screws employed to attach the plate to the shoe nor to the shape or position of the tenon 3 and its-corresponding. mortise 4. We prefer, however, that the tenon 3 shall project from the upper surface of the base-plate 2 at a right angle thereto and enter a corresponding mortise,

this being the .simpler and cheaper construc'- placed cent-rally of the base-plate is employed, while two tenons are used occupying the positions of the screws in Fig. 1.

This invention admits of the attachment to the shoe of calks of any character, whether blunt, smooth, roughened, or constructed with non-slipping material, the object being to provide a simple and secure fastening for calks of any variety and for their ready removal, so that calks of other type may be as readily substituted. 7

In Fig. 11 are seen three equivalent forms of the recesswhich receives-the base-plate of the calk, the sides of the recesses being vertical and not undercut, as in our earlier patent, No. 822,541. Each of therecesses shown in Fig. 11 is adapted to receive a baseplate of corresponding-shape.

In the modification shown in Fig. 9 the base-plate may be let into or countersunk into the under surface of the shoe, for the countersink which receives the base-plate 'of the calk may be of a depth equal to the Ioo ing-screws are subjected in the practical use of the shoe are greatly reduced. I

We do not restrict ourselves to the eXact details of construction, combination, and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by the skilled mechanic, and such departures from what is herein described and claimed not involving invention we consider as within the scope and terms of our claims. Having thus described our invention, we

cl aim 1. The combination of a horseshoe having amortise and a threaded aperture, a calk having a base-plate provided with a tenon adapted to fit: in the mortise of the shoe and a countersunk aperture adapted to aline with the threaded aperture of the shoe, and a H screw having a central polygonal opening and a conical head, said screw being fitted to the apertures of the base-plate and shoe, respectively, and flush with the under surface of the base-plate, substantially as set forth.

2. The combination of a horseshoe having threaded apertures and provided with mortises, toe and heel calks having base-plates tenonedinto the mortises of the shoe and furnished with countersunk apertures adapted 'to aline with the threaded apertures of the shoe, and conically-headed screws having central polygonal openings, said screws being fitted to the alined apertures of the baseplates and shoe, respectively, and flush with the under surfaces, of the base-plates, substantially as set forth.

3. The combination of a horseshoe having a mortise, a threaded aperture and an under countersink or cavity, a calk having a baseplate adapted to be seated in said countersink or cavity, a tenon capable of fitting in the mortise of the shoe and a countersunk aperture in alinement with the threaded aperture in the shoe, and a screw having a central polygonal opening and a conical head,

, said screw'being fitted to the alined apertures of the baseplate of the calk and the shoe, respectively, and flush with the under cavities, toe and heel calks having baseplates adapted to be seated in said countersinks or cavities and tenoned into the mortises of the shoe and also furnished with countersunk apertures adapted to aline with thethreaded apertures of the shoe, and conicallyheaded screws having central polygonal openings, said screws being fitted to the alined apertures of the base-plates and the shoe, respectively, and flush with the under surfaces of the base-plates, substantially as set forth.

5. The combination of a horseshoe having threaded apertures and provided with mortises, toe and heel calks havin base-plates tenoned into the mortises of t e shoe and furnished with countersunk apertures adapted to aline with the threaded apertures of the shoe, and screws fitted to the alined apertures of the base-plates and shoe, respectively, and provided with central polygonal openings, substantially as set forth.

6. The combination of a horseshoe having a mortise, -a threaded aperture and an under countersink or cavity, a calk having a baseplate adapted to be seated in said countersink or cavity, and a tenon capable of fitting in the mortise of the shoe and a countersunk aperture in alinement with the threaded aperture in the shoe, and a screw fitted to the alined'apert'ures of the base-plate of the calk and the shoe, respectively, and provided with a central polygonal opening, substantially as set forth.

7. The combination of a horseshoe having threaded apertures and provided with mortises and having also under countersinks or cavities, toe andheel calks having baseplates adapted to be seated in said countersinks or cavities and tenoned into the mortises of the shoe and also furnished with countersunk apertures adapted to aline with the threaded apertures of the shoe, and screws fitted to the alined apertures of the base-plates and the shoe, respectively, and provided with polygonal openings, substantially as set forth.

In testimony whereof we afliX our signatures in presence of two witnesses.
